Medical marijuana patients are free to have their drug on college and university campuses without having to fear arrest, the Arizona Supreme Court ruled this morning.

The justices said the 2010 Arizona Medical Marijuana Act gave those who have certain medical conditions permission to obtain up to 2 1/2 ounces of marijuana every two weeks.

That law also said the initiative sets out specific places where even those entitled to otherwise use the drug legally may not have it. That includes school buses, public schools and correctional facilities.

“This is an incredibly important victory for Arizona patients, ensuring they are protected from criminal prosecution when in possession of a medicine which they have the right to possess and consume pursuant to our laws and administrative rules.”
